Pearl Jam might be the unlikeliest band to cover "Let It Go," the Oscar-winning number from Frozen.

Be that as it may, the rock group surprised fans by launching into the song's chorus in the midst of its performance of "Daughter" on stage at Stadio San Siro in Milan, Italy, Friday. Frontman Eddie Vedder, who has two young daughters, belted out the Disney tune in front of thousands of adoring concertgoers.

Idina Menzel, who voiced Queen Elsa in the animated movie, scored her first Top 10 hit with "Let It Go." Demi Lovato performed a pop version for the soundtrack, and YouTube users have often covered the track. Meanwhile, since its release in 2013, Frozen has become the fifth highest-grossing film of all time.
